Hi Doctor,

As a sample running haven for 1.6.8 vs 1.7.0, I am using gpu card asus rog rx580 8gb, memory type micron

My Mem Strap : 777000000000000022AA1C0073626C41B0551016BA0D260B006AE60004061420EA8940AA0300000 01914292EB22E3B16 (From Pimp SRBPolaris)
cclock/mclock : 1160/2200
AMD Driver     : 18.6.1

using 1.6.8 I can get stable @1052
using 1.7.0:
   { "id" : 0, "intensity" : 59 , "worksize" : 8, "fragment" : 4, "threads" : 2},

        the same config using various "fragments" :
        ==> 0 = 906 ,1 = 1009 , 2 = 911 , 4 = 1010 , 8 = 1007 , 16 = 1009 , 32 = 1010 , 64 = 1005, 128 = 966

using fragment 4 with "worksize" = 08, various intensity : 59=1011 58=1000 57=997 56=891 55=882 54=886 52=972 48=958
using fragment 4 with "worksize" = 16, various intensity : 59=0908 58=0903 57=897 56=      55=      54=     52=867 48=840
using various "aes", the result is no different, but default/0 more stable

using config suggested here :
   { "id" : 0, "intensity" : 58 , "worksize" : 16, "fragment" : 4, "threads" : 2} = 903
   { "id" : 0, "intensity" : 59 , "worksize" : 8, "fragment" : 4, "threads" : 2}   = 1000

any more suggestion?

Thanks.
